Task Instances

Each time a Task is executed, a Record called a Task Instance is created to track that execution.

Task Instances help you monitor Workflow activity and review the outcome of individual Task executions.

You can monitor Task Instances on the Task Instances Dashboard.

Statuses

A Task Instance can have only one of the following statuses at a time:

Status	Description
Pending	The Task Instance has been created, but execution has not started yet.
Running	The Task Instance is currently being executed.
Completed	The Task Instance finished successfully.
Failed	The Task Instance did not complete successfully. Any remaining Task Instances assigned to the same Trigger are marked as Aborted, and On Error Tasks are triggered.
Aborted	The Task Instance was not executed because a previous Task Instance in the same Trigger failed.

Viewing the Task Instances Dashboard

To view the Task Instances Dashboard, click Monitoring > Task Instances from the Sidebar. The dashboard displays a table of Task Instance Records.

The Task Instances table automatically refreshes every 10 seconds. You can also manually refresh the table at any time by clicking the Refresh button in the top-right corner.

There are various ways to customize your view of the Task Instances table.

As with any Record Table, you can toggle which columns are displayed by clicking the Columns button above the list (see Selecting Columns).

You can further customize how the Task Instances table is displayed through:

• Sorting
• Filtering
• Searching

Sorting

By default, the Task Instances list is sorted by the Completed column. As with any Record Table, you can sort by a different field by clicking the corresponding column header.

Filtering

UDMG displays up to 80,000 of the most recent Task Instance Records on the Task Instances Dashboard at once. Filtering allows you to narrow this list down to a smaller set of Records.

You can filter the Task Instances Dashboard by Time Filter and Status.

Time Filter

You can filter Task Instances by start time by clicking the Time filter above the table, to the right of the Search bar.

Select one of the following times:

• Time (no time filter applied)
• 5 minutes
• 10 minutes
• 30 minutes
• 1 hour
• 12 hours
• 24 hours
• 48 hours
• 1 week
• 2 weeks
• 1 month
• 3 months
• 6 months
• 1 year

Status Filter

You can filter Task Instances by Status by clicking the Status filter above the table, to the right of the Time filter:

Select one of the following statuses:

• Status: All
• Pending
• Running
• Completed
• Failed
• Aborted

Searching

You can further filter Task Instance Records by using the free text functionality of the Search bar. When you enter text in the Search bar, UDMG searches for matching values in the following columns:

• UUID
• Transfer UUID
• Task Name
• Status
• Pipeline
• Started and Completed (for example, searching 2026-04-10 returns Task Instances that were started or completed on April 10th, 2026)

The Search bar applies only to Task Instance Records that are currently loaded in the table, across all pages. For example, if 1,000 Task Instance Records have been returned, the Search bar searches only those 1,000 records.

Managing Task Instances

Viewing Task Instances Details

To view the details of a Task Instance, follow these steps:

1. From the Sidebar, click Monitoring > Task Instances.
2. Click the Task Name of the Task Instance Record you want to view.

Task Instance Metadata

Task Instance details include the following read-only metadata:

Name	Description
UUID	Universally Unique Identifier of this Task Instance.
Status	Current Task Instance status.
Transfer UUID	Universally Unique Identifier of the Transfer associated with the Task execution.
Trigger	The Trigger that caused the Task to be executed.
Task Name	The name of the Task executed.
Order	Execution order of the Task within its Trigger.
Pipeline	Name of the Pipeline whose Workflow executed the Task.

Viewing Task Instances Output

To view the output of a Task Instance Record, follow these steps:

1. From the Sidebar, click Monitoring > Task Instances.
2. Click the Task Name of the Task Instance Record you want to view.
3. Click the Output tab.

The Output tab displays the output generated during the Task execution.

Output Truncation

To prevent performance issues, Task Instance output is limited to 64 KB. If the output exceeds this limit, only the last 64 KB is stored. In that case, the output is prefixed with the message ... (output truncated, showing last 64KB).

Output truncation occurs before the output is stored, and truncation events are logged for debugging purposes.
